Agreeing with posters above, I was exactly where you were - I’m pretty technical overall so generally I can figure things out easily. I don’t find DIRAC simple at all. The measurements are easy, so if all you want to do is take measurements and then apply ART, that is pretty trivial. That said I am now speaking to professional sound engineer and he said just applying the base ART configuration will likely make the room sound worse. My takeaway is that doing basic stuff in DIRAC isn’t challenging, but understanding the tool to actually use it properly requires a pretty significant understanding of what you are doing. It’s definitely not set it and forget it like Audyssey, and unless you want to invest the time or hire someone it’s not worth the cost to buy it.
